This week, a new enzyme speeds up the breakdown of plastic bottles, and a method to cool molecules to a fraction above absolute zero.In this episode:01:18 A PET recycling enzymeResearchers have engineered an enzyme that effectively breaks down the plastic PET into its constituent monomers. This could allow for more complete recycling of bottles and clothes.

Research Highlight: Humans opt to brave electric shock to satisfy their curiosity; Research Highlight: Munich’s Oktoberfest is a real gas09:15 Supercool moleculesResearchers have used a technique called ‘collision cooling’ to chill molecules to a few millionths of a degree above absolute zero, which could allow observations of difficult-to-study quantum mechanics. Research Article: Son et al.14:46 Research HighlightsNeither supermassive, nor super small, the mystery of the elusive intermediate sized black-hole has been solved.
